Is present if there are elements that allocate two value ranges of an input signal in a steady state to two different values of the output signal (two-point elements) (DIN 19 226).

Measurement technology : Device that converts a continuous measurement signal into a pulsating alternating current. Hydraulic systems : In the same vein, the chopper is used for hydraulic devices, cre

Combination of various devices that carry out one or more functions.

Term from circuit technology. If a valve in the bypass (secondary flow) is switched, then it opens a flow path for the flow rate bypassing the rest of the control arrangement.

Controller with digital signal processing during which the continuous change in the controlled variable is sampled in steps. For the processing it is necessary to change to discrete time operation. If

Device for separating small particles of dirt from the hydraulic fluid based on other particle characteristics apart from the particle size.

If the state variables required for a state controller State variable cannot be measured or are difficult to measure, this can be replaced by monitoring the behaviour of these variables (Figure Z 9).

Interaction between a spring-loaded mass system (e.g. cylinder + oil column + load) and the pressurisation at very low sliding speeds ( Figure S 94 ). The stiction of the system –– which is primarily

The part of a valve , which ensures the desired function through its movements.

whereby the control algorithm is associated with non-linear behaviour, i.e. the input and output for the controller are linked to each other by a non-linear characteristic curve or function.
